How to understand that a dog has gone into heat? - briefly
To determine if your dog is in heat, look for signs such as swelling of the vulva and a slight discharge of blood or mucus from the vagina. Additionally, male dogs may show increased interest in her, indicating that she is releasing pheromones.
How to understand that a dog has gone into heat? - in detail
Understanding when a dog is in heat involves recognizing several physical and behavioral changes. Here are some detailed signs to look out for:
-
Vaginal Discharge: One of the most noticeable signs that a dog has gone into heat is vaginal discharge, which typically appears pink or blood-tinged at first. This stage is often referred to as proestrus and usually lasts about 9 days. As the cycle progresses, the discharge changes color, becoming lighter and straw-colored during estrus, the period when the dog is most fertile.
-
Swelling of the Vulva: Along with vaginal discharge, you may notice that your dog's vulva becomes swollen and red. This is another indication that she has entered her heat cycle. The swelling usually subsides as the cycle progresses.
-
Behavioral Changes: Dogs in heat often exhibit behavioral changes that can be quite noticeable. These may include:
- Increased urination to mark their territory and attract males.
- Restlessness or agitation, especially when trying to get comfortable.
- Clinginess or increased attention-seeking behavior from her owner.
- Aggression towards other female dogs.
- Mounting behavior, which can be directed at other dogs, toys, or even people.
-
Nesting Instinct: As the heat cycle nears its end, some dogs may display a strong nesting instinct. This can involve shredding bedding, digging, and generally preparing a safe space for potential puppies.
-
Change in Appetite: Some dogs experience a decrease in appetite during their heat cycle, while others might eat more than usual. Monitor your dog's food intake to ensure she maintains a healthy weight throughout this period.
-
Lethargy: It is not uncommon for dogs to become less active or more tired during their heat cycle. This can be due to the hormonal changes they are experiencing.
It’s important to note that each dog may exhibit these signs differently, and some dogs might show only a few of them. If you notice any of these changes in your dog, it's advisable to consult with a veterinarian for personalized advice on how to manage her heat cycle effectively.
